IFN-γ-augmented apoptotic gene expression. (A) Heat map of apoptotic gene expression in normal B6 BM cells cultured for 20 hours with 50 ng/mL IFN-γ (IFN-γ) or media only (control). (B) Differential expression of apoptotic genes in B6 BM cells after 20 hours of culture with 50 ng/mL IFN-γ (IFN-γ), 50 ng/mL IFN-γ + 1 μg/mL anti-Fas antibody (anti-Fas), or media control (control). (C) Apoptotic gene expression heat map for KSL cells from B6 donors after 20 hours of culture with or without 50 ng/mL IFN-γ. (D) Apoptotic gene expression heat map for KSL cells from B6 mice with or without IFN-γ injection (10 µg per mouse) 20 hours earlier.
